AsyncHttpClient错误中使用的同步ResponseHandler

Question

最后一天,我正在尝试使用我的asynchttpclient修复错误,但我创建的帮助并没有解决问题.希望有人可以帮助我.错误是当我启动服务时,我希望该任务总是使用php进行SQL查询并且它接收我稍后将使用的参数.

感谢未来的帮助!!

错误"AsyncHttpClient中使用的同步ResponseHandler.您应该在循环线程中创建响应处理程序或使用SyncHttpClient." 提示问题是什么.

因为在这种情况下你想使用AsyncHttpClient而不是SyncHttpClient,你需要使用looper线程.

Handler mainHandler = new Handler(Looper.getMainLooper());
Runnable myRunnable = new Runnable() {
           @Override
            public void run() {
                //Code that uses AsyncHttpClient in your case ConsultaCaract()
            }
        };
mainHandler.post(myRunnable);
